A clever device to prevent rattle and the sash from fallingis the gravity wedging lock. The lock bolt is beveled 45degrees and settles into a corresponding downward and out-ward beveled rack. A gradual wedging of the sash againstthe stops in its downward movement effects a gradual stop,preventing the usual sudden jar, which loosens the screwsand fixtures, breaking glass, etc. The sash is securely lockedagainst the outside stop in a peculiar manner, preventing allrattle and accidents by falling. Various designs of these racks are made, some of whichare shown in these cuts. The pressed rack appears espe-cially neat, as it sets flush with the stop. The designs costno more than the ordinary continuous rack. The individualstops also show the anti-rattle wedging feature and are re-.
